git commit -am "Use ConfigMaps" && git push origin dev

Whoops! Type in index.js!

git commit -am "Fixed Type" && git push origin dev

Tests Pass! Squash and Merge into Master!

Whoops! Forgot to create the ConfigMap

kubectl create configmap data --from-file=./data/data.json

(Optional) Update ConfigMap

kubectl create configmap data --from-file=./data/data.json -o yaml --dry-run | kubectl replace -f -

Reset Demo

git checkout v1.0 && \
git branch -D master && \
git checkout -b master && \
git push -f origin master
